关于ubuntu的各种学习资源，十分齐全(With regard to ubuntu a variety of learning resources, a very complete)

快速计算一维信号的塔式谱峭度图，选择谱峭度最大值区间，方便确定所需滤波器中心频率及带宽。(Computes the fast kurtogram of signal x.This fast algorithm uses a pyramidal decomposition of the signal into a user-specified number of levels (a good choice is nlevel = 8). The first level is the classical kurtosis of the signal, the second level is the spectral kurtosis in 2 octaves, the third level the spectral kurtosis in 4 half-octaves, etc. Non-integer levels refer to divisions into third octaves. Here below is an illustration on how the frequency band is successively split when increasing the level)

有限元matlab程序，包括二维、三维网孔划分、网孔选择、边界等(Finite element matlab program, including 2D, 3D mesh division, mesh selection, borders, etc.)

时间序列在MATLAB中的应用以及使用说明(Time series in MATLAB applications and instructions for use)

基于matlab语言环境下的暂态上机计算对称电流和不对称电流故障的计算(Based on the transient in the matlab language environment on the calculation of the symmetrical current and asymmetrical current fault)

In cryptography, SHA-1 is a cryptographic hash function designed by the United States National Security Agency and published by the United States NIST as a U.S. Federal Information Processing Standard. SHA stands for "secure hash algorithm".

关于卡尔曼滤波器进行时间序列的预测，有助于初学者的学习(Predictions about the Calman filter for time series, will help beginners to learn)

鲁棒主成分分析 低秩与稀疏矩阵分解 增广拉格朗日 图像重建、去噪(robust pca low-rank and sparse matrix decomposition)

Auto robots in the matlab environment.

四个机器人，实现编队行走，遇到障碍物后变换队形，实现避障，基本思想是利用栅格法。(Four robot, achieve the formation of walking, encounter an obstacle after the formation and transformation, to achieve obstacle avoidance, the basic idea is using grid method.)
